Today, works on a virtual coloscopy not requiring the purgative one but using a solution which marks the food remainders remaining in the intestine in order to distinguish them from the polyps. The effectiveness of this technique is 85 to 88% for the detection of the polyps of one centimetre. As for the radiologists, they still seek to reduce the exposure to the radiations caused by the virtual coloscopy.
An article about ocular
microsurgery. Among other problems, the eye occupies the second place in the
United States as regards blindness.
In the family of Bill the diabetes was an endemic disease: their greats-grandfather
to pater and their paternal grandfathers to us contracted diabetes of adults.
Bill began to suffer the disease before turning 3 years. To the 8 years, single
it put the insulin injections, beginning therefore a strict, but essential routine
for his health.
Probably this discipline delayed the appearance of the ocular microsurgery, a pernicious complication and burdens of the eye that affects to almost all the patients with youthful diabetes between the 15 and 20 years. Bill did not have problems with the Vista until it was about 30 years old, and thanks to that the Vista was examined periodically, diagnosed the disease on time to him. Fotocoagulación by laser (procedure by which a series of small burns with laser around the periphery of the retina is made), sealed the irregular growth of the blood vessels.

According to specialists, approximately 143.300 new cases will have been detected in 2002, whose 56.000 people will die about it. Ocular microsurgery is recommended, If 90% of the patients can be neat definitively using a coloscopy and ablation of the polyps, two thirds of the old people of more than fifty years are not subjected for the examinations by necessary routine to the tracking of this disease, mainly because of discomfort that those involve. Ocular microsurgery, with a new method of tracking, consistent in a radiography, makes it possible to detect 90% of the polyps exceeding the size of one centimetre and 75% of the less important polyps.
These results were obtained at the time of a study undertaken on 600 patients by veterans doctors. With a cost ranging between 500 and 1 000 dollars, this virtual technique appears much more economic than the traditional coloscopy invoiced between 1 000 and 2000 dollars. Alas, ocular microsurgery it is still not recognized by the insurance companies.
What can cause blindness if does not treat on time. In 1992, Bill had an operation eyes both, a procedure that can be carried out in the same consultation of the doctor just by to apply the light of the laser through the expanded pupil. "I am put under this process four times to the year", it declared Bill few years later, and added that the doctors are very content with the results. In the autumn of 1997, an industralist of 57 years of called age John awoke a morning seeing floating flashes of light and small points or bodies. As on the following day he continued seeing the same, he went to an ophtalmologist. They diagnosed later vitreous loosening to him of and a small laceración in the retina, and recommended ocular microsurgery for the patient . Vitreous humor, a liquid gelatinous transparency and that fills the inner camera of the eye, tends to degenerate itself during the mature age, it shrinks and it leaves the retina.
